So, to begin with, it's important to figure out why your score has been fluctuating so much. Gather all of the data you can about the different practice tests: whether you did the essays, whether you took them under official timing conditions (including the breaks), what time of day you took them, whether you'd taken another practice test within a few days before or did something else that would have tired you out or stressed you out - basically anything that could have possibly caused a blip in your scores (positive or negative!). Also pay attention to whether you ran out of time significantly on some tests. Then, put it all together to see if you can figure out a pattern.
Also, are both quant and verbal fluctuating a lot? Or are the differences mostly due to one section changing a lot?
Second, you've got about 3 weeks until Oct 7th. What is your goal score? You say "high" but that could mean 680 - in which case, you are at least sometimes in that range already, and our task is just to figure out what's causing the fluctuations and stop them. Or you could mean 720 - in which case, you are not yet in that range, and we need to figure out both how to stop the fluctuations AND how to improve your score beyond that.
So, at the least, we do need to figure out what's causing the fluctuations and stop that. I'll address that here; if you also want to improve beyond that, let me know. The most common causes:
- timing: running out of time at the end; alternatively, not running out of time, but still spending too much time on some questions and rushing on too many others as a result (if you notice LOTS of careless errors, then timing may be part of the culprit)
- stamina: most people do better (especially on the verbal) if they skip the essays, if they take longer breaks than allowed... basically, if they don't take the test under full official conditions; people also tend to do worse on the later tests when taking two or three tests in two or three days, or when taking tests after a long day at work
Now, in your error log - what exactly are you including in the log? The most important thing is to note (1) WHY you made the mistake you made, and (2) what habit you are going to make or break to minimize the chances of making that same kind of mistake in future. It's not enough just to do the problem again.
Re: materials
- I am NOT a fan of 1000 SC. There are a lot of better materials available. I would first use OG 12, OG Verbal Supplement 2nd edition, OG 11, OG 10, OG Verbal Supplement 1st edition, GMATPrep, and MGMAT stuff. Beyond that, if you haven't learned what you needed to learn, then you should actually go back over that material again, rather than use questionable sources. Re: your question about how to decide between Kaplan 800 and OG12, I haven't used Kaplan, so I can't comment directly, but here's how to decide: if you want the best possible practice problems, use OG12 (I'd say this in a direct comparison between OG12 and MGMAT's stuff, too!). If you are trying to learn how to get better at some type of problem, then use the test prep company's stuff (Kaplan, MGMAT, whatever).
- I wouldn't do more than one practice test a week. CAT exams are really good for (a) figuring out where you're scoring right now, (b) practicing stamina, and (c) analyzing your strengths and weaknesses. The actual act of just taking the exam is NOT so useful for improving. It's what you do with the test results / between tests that helps you to improve. And from any one test, anyone can set up at least a one week study plan (if not longer) based upon the strengths and weaknesses from that test.
- I wouldn't use the retired GMAT paper tests for anything other than an additional source of practice questions (similar to OG). Don't take them as full practice tests - that's not how the real test works anymore and, in some cases, the best way to take a paper test is NOT the best way to take a CAT.
- at this point, your review should be planned based upon the specific strengths and weaknesses you're noticing from your practice. It is a good idea to group things, as you suggest, eg, today, I will review all of the issues I've been having with geometry, but I'm not going to review ALL of geometry. Just the things that need review / work, based upon the results of my practice.
